[syedjilani]

I need your help and suggestion guys. I got same coral Pink Stylophora, when I got this coral it was same as in photo below form live aquaria. Can anyone tell me what kind of lighting it require, what kind of flow it need, Feeding, any special element in water column, any special instruction. Etc. etc….

I am not able to get this color back.
You can have look on my thread “ My 300G Reef in Saudi Arabia” http://www.reefcentral.com/forums/sh....php?t=1849903

I post this problem on page # 20, some is suggesting to lower down this coral from strong light and another is insisting to raise it up with strong flow.
Your suggestion will be highly appreciated.
